427 block and head codes needed

[skierkaj]

I recently came across what was supposed to be a 427 block, with rebuilt heads. The motor had all the bottom end components, but looks like it hadn't been touched (except for the heads) for 30 years. No intake, carb, etc., but it still looks promising. Could you guys help me with some codes I should look for, to insure that this motor is genuine, before I lay down the cash?

Here is a site where you can check casting numbers. Post the numbers off the engine pad.
